A. Both parts of this biconditional statement are true, so by the truth-table definition this is a true statement.
B. Both parts of this conjunction are true, so the statement is true.
C. The second part of this disjunction is true, so the statement is true.
D. The hypothesis of this conditional statement is false and the   conclusion is true, so by the truth-table definition this is a true statement. (Either of those conditions would have been enough to make the statement true.)
